ppc/pnv: SMT support for powernv
Set the TIR default value with the SMT thread index, and place some standard limits on SMT configurations. Now powernv is able to boot skiboot and Linux with a SMT topology, including booting a KVM guest. There are several SPRs and other features (e.g., broadcast msgsnd) that are not implemented, but not used by OPAL or Linux and can be added incrementally.
